Hi guys...
Joying has recently been selling devices with Android 10.
Is it possible to install this version (Android 10) on my JY-UO134N4GS model device with Android 8.1?
Thank you

Extract Allapp.pkg and delete whichever app you want then repack before installing the new firmware

Hello. I am looking for information on how to completely disable the CarInfo app on my head unit. I believe I have some sort of short in the Canbus interface for my VW Tiguan. The result is that the Air Conditioning status overlay appears randomly (usually only in the first 15-20 minutes of driving the car while it's warming up). This was only a mildly annoying problem. And long ago I have disabled the air conditioning overlay in the Car Agreement menu.

However, now I have the same problem with the CarInfo app. It randomly will appear just like the air conditioning overlay used to (usually in the first 15-20 minutes of driving). But the problem with CarInfo is that it is not an overlay. It takes over as the active window and creates other significant problems while driving. If there is a way to fully disable this app, I would really like to do so. It seems not to be an app that I can simply uninstall. Any thoughts on this? I am fully rooted by the way. Thank you in advance for your help.

Anyone? Just looking for information on how to completely disable an app. Or if you have other suggestions, I'm all ears. I'm also considering taking the car to the dealership to see if I can get the canbus repaired/replaced. But I'm concerned that this is going to be expensive (perhaps not). Thank you.

The carinfo app IS the canbus app (com.syu.canbus), but just started by the default intent/activity instead of the background activities/intents.
If you completely disable it, you will also completely disable all canbus functionality.
Is that what you want?

Hi surfer. Thanks a lot for the reply. I was not aware that disabling this app would disable all canbus functionality. After giving this some thought, I think losing the steering wheel controls will be even more disruptive. Given that this car will soon be turned over to my wife (and I want to make it as wife-friendly as possible), I think I will investigate what it would cost for my local VW garage to debug and fix this 'short'. Thanks again for your reply.

Just picked one of these units up on Amazon for a bargain price.

Is the latest stock rom from joying good? Or is there a better custom rom I should be looking for?

The latest stock rom is fine, although it still contains errors (like any of these chinese firmwares)
There is no custom rom available. The udt team delivers modified apps and launchers, but I consider that simply as the same firmware with different layout and slighlty moderated launchers, but with the same bugs. If you like their layouts, this is a good option to go for.
You could even install a firmware from T'eyes on your Joying with some tweaks, but I would not advice to do that. It will cripple your unit as the "extra's" need to be paid for and as a Joying user, T'eyes will never allow that.

My personal recommendation is to use the standard rom and use some of the apps available here like the fytstarter and hwonekey (in case of hardware buttons on your unit) or the continued development of that latter one.
I used to be an active modder, but already for a very long time I use the default unrooted ROM with only the "extended" main app.

Thanks for the advise. I think I'll stick with the main rom for now by the sounds of it. Ill just make sure to update it.
What's the extended main app you mentioned ?

Thanks heaps. Just had a look and I think I'll just stick with stock firmware and apps for now. I don't plan to do anything crazy and this is my first android headunit so it's already a big jump from my old cd. Player.

Just planing to use Spotify, Google maps, the OBD2 scanner with torque pro, and the joying ADHD reverse cam.

Might introduce the tpms and dashcam later. Given that their are only 2 USB ports, are there any USB hubs you you would suggest?

Depends on the power requirements. There are powered hubs that can be connected to 12V. These are the best. There are many of them.
One thing to consider is that cheap usb hubs (aliexpress) might produce "noise" that will/might influence other equipment.

    Has anyone tried the root method reposted from the Russian site? Building up to trying it, but if it's been tried and doesn't work it would be good to know.

    Just got it working on my HU!
    We're rooted!! :D:D:D

    For reference, I am using the factory image I posted way back on page 5.

    A few notes about the installation:
    1) Magisk Manager does not work with the stock File Manager
    -When you go to patch the boot image, Magisk Manager crashes
    -I rebooted my device and installed "File Manager" (the ASUS one, but shouldn't matter) from the play store
    -Next I force-stopped Magisk Manager
    -Finally I re-opened Magisk Manager and was able to select my boot.img to patch.

    2)Start.bat file in Root.zip points to the wrong zip file, so after you add "patched_boot.img" to the archive, rename the archive from"6521_1_input.zip" to "input.zip".
    -Alternatively you can just change the single line in the batch file to the correct filename :p

    If anyone's interested I can probably type up a longer step-by-step howto and post it tomorrow.

    Happy rooting!

    Does anyone have an idea how to totally wipe the unit? twipe_all doesn't seem to cut it. (I also pushed some LCD configuration from one of the older versions, but to no avail)

    Hi, today i got an e-mail from joying as below;

    Dear friend,

    According to the button light problems, there is a resolved file come out, please check and update: https://drive.google.com/open?id=1_Hfn-vFb0MDqeWOzqC9Jn3JI2HRj3F_0

    I have downloaded and examined the files by checking crc sha-256 and all of them identical as 14-08-2019 update except Stm32ud.bin file which is mcu. So no need to download again 1gb update file for update. Just extract below attached file and put them in to the usb then unit will update itself without loss of data. You can keep all the settings without losing anything.

    Normally joying should advise above procedure to prevent unnecessary loss of time instead every time advising full update but i already lowered my expectations :D

    Cheers.

    Since this a one of those things that people wanted , I am going to make a new topic to give full details...
    You have to be rooted first..then go to the root directory, them oem folder, them in the config.txt you will see a line (i forgot exactly ) but something like..com.fyt.bt = "1"
    set it to "0"
    and then save and reboot.
    if you have the new latest updates, the bluetooth setting in the android menu will disappear (at least on mine it did).. you can use a third party tool to show the bluetooth setting if you want to see and pair devices from there.
    Or you can just use the conventional way .. (the default bluetooth app )
    on the 4pa forum, I read if setting it to 0 doesn't work you can try different numbers up until 5.
    Please give it a show and let me see if it works for ya. :)

    OK,

    So it is config.txt in /oem/app and the value is "sys.fyt.bluetooth_type=1".
    For those who are rooted they can follow @ojuniour method.

    For those who are not rooted (like myself as I don't want it): That is also a very simple action. (Edit: and also rooted users can use that method)
    Unzip attached zip file to a clean USB-stick. It only contains the config.txt and lsec6521update. Use this to flash your device. It will be a superfast flash only updating the config.txt (please don't fear the maybe scary messages about "resetting to factory defaults". I does not do that, it is just a message from the flash program for a "normal" flash).
    It is actually the exact same approach as I described in "Modding your Joying/FYT SC9853i unit without root" in the first 3 posts.
    The config.txt contains the value "sys.fyt.bluetooth_type=0". Simply replace by 2-5 if it doesn't work and flash again, like described in the 4pda topic @ojuniour referred to (Thanks again for that).

    Note: After reboot I took my bluetooth keyboard in the car and tried to connect with the BT app. It did find the keyboard and wanted to link it, but stayed on "linking", without actually linking.
    So I installed "Bluetooth Pair" from Waylon Huang (simply the first in my search in the play store) and with that one I could successfully pair my BT keyboard (and type 10x as fast as with the onscreen soft-kyboard)

    More tests will follow.

    Try those from the Flyaudio Intel Airmont devices https://forum.xda-developers.com/showthread.php?p=79415422

    Factory Settings: 3368

    Developer Settings: 3368

    Backlight current adjustment: 5768

    Door lock interference: 0000

    I assume the system apps are very similar, if not equal.

    Google voice control/assistant works except there is no voice feedback (assistant answers but there is no voice)


    Easy to fix.
    Open 190000000_com.syu.ms.apk with 7zip or winrar or simmilar. Just open , no need to unpack.
    Go to assets\app_category
    Open voice_app.txt and delete or comment out everything with "#"
    Code:
    #语音应用,语音应用在录音时需要机器临时静音,以免干扰录音,影响识别效果
    #通常语音应用录音开始时会请求Audio Focus,该文件中适配的应用,在申请Audio Focus时
    #服务会做相应的音频处理,释放Audio Focus时恢复到当前状态声音输出
    com.google.android.googlequicksearchbox #Google语音
    com.txznet.txz
    Save the file back in the archive and copy apk back to \oem\190000000.com.syu.ms.
    Reboot and enjoy assistant voice answers.
